HYDRGGEN LAWlP.

SPECIFICATION forming part of Letters Patent No. 432,590, dated July 22, 1890. Application filed February 9, 1889. Serial No. 299,244. (No model.)

To (ZZZ whom, it may concern.-

Be it known that I, FRANK. AURNHAMMER, a citizen of the United States, residing in l'lolyoke, in the county of Ham pden and State of Massachusetts, have invented new and useful Improvements in Hydrogen-Lamps, of which the followingis a specification, reference being had to the accompanying drawings and letters of reference marked thereon, in which- Figure 1 is an elevation in section on line 00 a. Fig. 2 is a like view taken online '6 t, and Fig. 3 is a top or plan View of the device.

Like letters of reference indicate like parts.

The constructionand operation are as follows: A jar is provided in which is deposited dilute sulphuric or other acid for the production of gas. To the top of the jar is secured a plate or cover Z), which may be cemented or otherwise tightly secured in position. A cap 0 is secured to the plate Z), preferably by being threaded and screwed therein, as shown. The cap 0 is provided with a part (Z, within which a valve or cock is properly'arranged. The plug e is provided with a collar g. An opening is provided in the cap, which extends downward from the location of the collar g and opens into the jar. A lifting-rod h is connected at one end with the collar 9 and at its opposite end with a pivotal lever i, pivoted at the point y. Arod j extends from the pivotal lever o to a block 7a, which block is of zinc or other material adapted to produce the desired results when immersed in the acid, the block being suspended or supported by the rod j. The lever 71 is provided with an arm m, upon which is mounted a coiled spring Z, which serves to maintain the lever 'iand parts attached thereto in their normal position, as shown in the drawings. The plug e is made tapering from the nozzle end downward, and is tightly fitted within the part (Z, and is provided with levers or arms f. The plugis also provided with an interior opening tapcringtoward the nozzle end, and isprovided with an opening 8, arranged to register with the opening 7' in the cap when the plug is turned to the desired position. To the plate or cover I) is secured a standard or, provided with a ring a, into which ring is fitted a thinible or cylindrical piece 0, and within the part 0 is arranged a platina sponge p. The

platina sponge and its support are of course arranged opposite the nozzle-opening of the plug 6.

Then the device is not in use, the operative parts remain in the position shown in the drawings. The block k is not, therefore, in contact with the acid, and no chemical action takes place, and therefore no loss results. \Vhen, however, it is desired to set the device in operation, the levers or arms f are revolved or moved a short distance, this causing the plug 6 to be turned, bringing the opening .9 in register with the opening 0', lowering the rod h, turning the lever 2' upon its pivot, lowerin g the rodj, and lowering the block 70, thus bringing the block in contact with the acid, when chemical action immediately results and hydrogen gas is evolved, which escapes through the openings 'r and s, and thence through the nozzle-opening of the plug 6 in a fine jet, impinging against the platina sponge p, which produces a flame. Immediately upon a release of the lovers f the spring Z operates to return the parts to their normal position and the production of the gas ceases.

Having therefore described my invention, what I claim, and desire to secure by Letters Patent, is

1. In an apparatus of the kind shown, the combination of a jar and cover fitting the same, the upper portion of the cover being projected upward and provided with a rotatable plug 0, provided with openings, as stated, and a hand-wheel f, mounted on said plug, a lever i, pivoted between its ends to a bar on the inner face of the cover, and provided with p a spring at, mounted upon an arm projecting from the lever i, a rod h, attached at one end to the lever 'Z and at the opposite end to the plug e, and a rod j, attached to the lever 'Z opposite the point of connection of rod h therewith, substantially as shown.

2. The combination of a jar a, cover 1), cap 0, provided with a part d, a plug 6, provided with openings and having levers f attached, collar g, mounted on the plug, rod h, lever '2', having arm m, with spring Zmounted thereon, rod 7', and block it, substantially as and for the purpose shown.
